Other signs of meningitis

There are additional signs and symptoms to look out for if you suspect you have meningitis. Early symptoms will be similar to the flu, and they can develop over a matter of hours or even days. Symptoms include:

Nuchal rigidity

A third sign used to diagnose meningitis is called nuchal rigidity. Nuchal rigidity is an inability to flex the neck forward due to rigidity of the neck muscles.

Similar to Kernig’s sign, research has shown that many people with meningitis don’t have the Brudzinski sign or nuchal rigidity.

The bottom line

Kernig’s sign, the Brudzinski sign, and nuchal rigidity are typically not successful at diagnosing those with meningitis.

While these tests can be done quickly at home, it’s important to seek immediate medical attention if you suspect you have meningitis. Early and definitive detection is extremely important in the treatment of this condition.

A lumbar puncture, also called a spinal tap, is a common and more effective way to diagnose a person with meningitis. Other diagnostic tools include CT imaging and blood cultures.
